SPECIFICATION forming part of 'Letters Patent No. 755,922, dated March29, 1904. Application filed July 2.9, 1899. Serial No. 725,506. (Nomodel.)

To all whom it may concern.-

Be it known that I, WILLIAM H. OsBoRN, a

citizen of the United States, residing at Louisville in the county ofJeiferson and State of Kentucky, have invented certain new and usefulImprovements in Water-Closets; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled inthe art to which it appertains to make and usethe same.

My invention relates to improvements in water-closet valves, moreespecially adapted for use in connection with the air-tight-tank type ofwater-closets usually supplied with water from the feed-pipe connectingwith the closet-bowl, although equally applicable to other types ofwater-closets.

One object of the invention is to controlthe supply and flushing actionof the water according to the pressureof the head of water;

the valves and to effect their ready adjustment.

A further object is to provide against the hammering action, which wouldotherwise arise in suddenly opening and closing the water or supplyvalve.

A further obj ect of the invention is to regulate orl control thepressure ofthe seat-arm valve-actuating device or set-screw, as may berequired.

A further object of the invention is to form a water-tight joint betweenthe valvespindle and the flushing-rim to prevent splashing of the waterat the inlet-point from the iiushingpipe to the rim.

A further object of the invention isl to construct and arrange the partsof the bowl and rim to produce a water-tight compartment at the pointwhere the valve is connected with the bowl for controlling the volume ofwater which may be directed either to the jet device or to theiiusliing-rim.

A further object of the invention is to secure a siphonic action in thecloset-bowl on the depression of the seat. y

Another object of my invention is to provide means which secures anequal distribution of the water for flushingthe closet-bowl throughoutpractically the entire area thereof-that is to say, through and aroundthe flushingl is a plan view of the bowl.

zontal sectional view on the dotted line d d of' lrim, over the innersurfaces of the bowl, and through the bottom part of the Siphon. f

A further object of the invention is to enable the ushing-rim toy beassembled to the ibowl, so as to secure a tight joint around theEwater-inlet nipple to the bowl and the supply- `chamber of theiiushing-rim, such joint being Vattained by the interposition of awasher between the bowl and rim and by the bolts which secure the rim tothe bowl.

A further object I have in view is to provide improved4 means actuatedby the seat for loperating the valve and stem, which valve-peratingmeans is controlled entirely and directly by the seat. 4

With these ends in view the invention consists in the novel combinationof elements and inthe construction and arrangements of parts,

which will be hereinafter fully described and claimed. also, tofacilitate the removal and renewal of In the accompanying drawings,Figure l is a vertical sectional elevation of a portion of a`closet-bowl and myV improved valve applied thereto. the line m m ofFig. l.

Fig. 7 Fig. 10 is a vertical transverse sec"-` tion on the dotted line0l l of Fig. 9, and Fig.

ll is a vertical sectional view on the dotted` IOO supplying the waterfrom a main or tank to said shell. Said shell has a gooseneck-likenozzle 3, to which is suitably connected a pipe leading to theflushing-tank. Said shell is coupled with the closet-bowl by screwingits inner threaded end into the bowl at 5, fitting a gasket 6 around theshell, and applying a collar 7 to said shell. A longitudinally-movablespindle or stem 8, arranged within the shell 1, is angular a portion ofits length and supported to slide freely and guided in acorrespondingly-shaped fixed guide 9 in said shell. One end portion ofsaid spindle is preferably cylindrical and enlarged, as at 9, andextends into the closet-bowl and carries a loosely-hungantifriction-roller 10, the function of which will appear farther on.Upon this stem or spindle are carried two valves, one being the supplyor water valve 8 and the other the fiushing-valve 8", seating in portsor seats 8c 8d, respectively, at opposite ends of the shellchamber, asshown in Fig. 1. Each valve 8*L 8lo consists of what I term a fullerball or plug of rubber or elastic material, adapted to be screwed onthreaded portions 8e 8f, respectively, of the stem or spindle 8, and ametal cap or socket 8g, fitted firmly on the outer end of each fullerball or plug and inserted upon said stem or spindle. Also arranged uponthe stem or spindle 8, bearing against the fixed guide 9 and a nut 9ELon said spindle, respectively, is a preferably helical spring 8h, whoseaction is exerted to automatically open the ushing-valve and close thesupply or water valve at the required time-z'. e., after the removal ofpressure from said stem at its roller end, as will be apparenthereinafter.

Upon the supply-valve end of the shell and opposite that end of the stemor spindle 8 is suitably held by a sectional or two-part screwcap 9b 9ca water-hammer device comprising aiiexible or rubber disk or diaphragm9d, secured between the parts of sections of said Cap, and a preferablycoiled or helical spring 9e, interposed between said diaphragm or diskand one of said sections, as shown in Fig. 1. Vl'hen the inlet or supplyvalve is suddenly closed, the high-water pressure caused by the suddenclosing of the valve will be relieved by coming in contact with the diskor cushion, and the spring behind the disk or cushion will atall timeskeep the disk or cushion in its proper shape after the high pressure hasbeen relieved.

Ascrew-cap 10, adapted to be screwed upon the ushing-valve end of theshell 1has preferably three or a series of ports through it for thepassage of the water from the supply'valve or chamber into thecloset-chamber when the flushing-valve is opened and also serves tocenter the spindle or stem 8 passing therethrough and as a guide inconnecting the shell to the hopper, as the shell is required to bescrewed or inserted into the hopper just acertain or predetermineddistance. The spindle or stem 8 is suitably packed where it passesthrough said cap 10 by preferably a flexible or soft-leather Washer 1laand wicking or fibrous material 111b sandwiched between said washer andcap, said washer coming in contact with the flushing-rim of the closetbowl or hopper, and thus tightly packing said fibrous or wickingmaterial against said cap, preventing any possible leakage or sprayingof water around said stem or spindle.l

It will be observed that by the use of the adjustable supply and Hushingvalves, as above described, either can be screwed or adjusted along thestem or -spindle 8 to any predetermined or required point with relationto its seat or port, according to the pressure of the head of water on,especially as found necessary in the use of air-tight or iron tanks, andthus regulate or control the supply and flushing action of said valves,preventing the excessive flow of water into the closet-bowl and thesplashing of the same out of the latter. Also by this arrangement thevalves can be readily adjusted, 'as is obvious, so as to increase thedischarging capacity of said valves, as required under a low pressure orhead of water to increase the otherwise reduced flushing action of thewater passing by the flushing-valve under such conditions.

A flat annular or ring-like casting 12 is suit- `ably secured by screwsor other fastenings tc the under side of the seat 13 and is adapted toform the hinge connection between said seat and the closet-bowl orBushing-rim, said ring or casting having preferably formed therewithparallel ears or sockets 12n 12 beyond the rear edge of said seat, andsaid flushingrim having parallel upstanding apertured lugs 12b 12badapted to enter said ears, and through these lugs and ears is inserteda pintle or nutted and headed rod 12, hinging or pivotally connectingthem together.

The ring or casting 12 is provided with a pendant or arm 12d, preferablyintegral therewith and arranged to stand in alinement with the valvestem or spindle 8, and is provided with a preferably fiat headed orshouldered setscrew 12", adapted to engage or contact with the roller 10to actuate said stem or spindle in closing the ushing-valve and openingthe i supply or water valve as the seat is depressed or sat upon tosupply the tank with water, the same also filling the valve-shell, sothat as pressure is removed from the seat the supply-valve will beclosed and the iushing-valve opened by the action of the spring 8h, thusproperly flushing the bowl and stopping 0H the supply of water atl thewater or supply valve. It will be observed that by the use of theset-screw, the same permitting of its relative adjustment to the valvestem or spindle 8, the seat can be caused to rest flush or flat down onthe flushing-rim or bowl and be free from all strain, while justsufficient pres- IOO IIO

sure is exerted as the seat is depressed or sat upon through the sameupon the flushing-valve to cut off the flow of the water to the bowl andalso relieve the valve of undue strain or any more than necessary forthat purpose.

- My improved construction of the valve provides means bywhich asiphonic action in the gooseneck-valve may be established when the seatis occupied. The water passing through the flushing-valve enters thecloset-bowl, in turn causing a siphonic action in the gooseneck-valveshell, siphoning water out of the bowl. y

- One of the leading features of myinvention consists in the employmentof a supply-chamber 13 on vthe flushing-rim 14: of thecloset. This rimis shown clearly by Figs. 9 to 11, inelusive, of the drawings. 1t is acontinuous cast-metal piece conforming to the shape of' the upper edgeof the closet-bowl 1, and at itsrear side, adjacent to a water-inletnipple 13a, the fiange 14a/of the rim isprovided with a curved wall 15,which is parallelto the rim and to the closet bowl and is joined. byflanges or walls to the fiushing-rim, so as to provide the chamber 13. yThis supply-chamber 13 lies between the bowl and the flange of theflushing-rim, and, as. heretofore described, the iange 1-1a ofthe rim 14has theI opening 141- to accommodate the valve-stem. The rear wall 15 ofthe flushing-rim has an enlarged opening 16, which is coincident or inalinement with the .opening 14h and the water-nipple, and thus thevalve-stem is-free to play in the openings 16 and the nipple. .Thesupplychamber 13 is ofv considerable area to insure a proper quantity ofwater being supplied to theflushing-rim and the bowl, and the dischargeof the water to the bowl and rim 14 is effected. through ports whichlead from the ends and bottom of .said chamber 13. The ports 17 areformed inthe end walls of anges of the chamber 13 todischarge directlyinthe space vinclosed between the iushing-rim vand the bowl, and the ports18 open downwardly through the bottom of the chamber 13 to direct wateragainst the inner surface of the bowl at the rear side thereof. I alsoconstruct the'bowl with a conduit or passage 19, which is formed on therear side of the bowl. This .conduit opens at its upper end into the vwater-nipple to receive water therefrom when the valve is opened and thecloset iiushed, and,

the lower endof this conduit extends to the bottom of the bowl anddischarges to a port 20 in a depression at the bottom of the bowl, so asto discharge-water into the siphon and assist the siphonic action of thecloset in carrying off the contents of the bowl.

It will be seen that I have provided an improved construction of thecloset bowl in which water is supplied from a single chamber to theiushing-rim and the bowl and by a conduit to the foot of the bowl, thusproviding a single source of water-supply tothree several parts of thecloset. l

To secure a tight joint around the water-inlet from the closet-nipple tothe supply-chamber of the iiushing-rim, I employ a gasket 21, which isinterposed betweenv the rear wall of the chambern13 and the closet. Thegasket surrounds the passage from the closet-nipple to the chamber, asshown by Figs. 9A and 10, and it isclamped in place between the wall15and the bowl when theflushing-rim is secured by bolts or screws .tothe-closet.

. It is evident that` slight changes in the form and proportion ofparts. and in the .detailed lconstruction maybe made without departingfrom the spirit or sacrificing the advantages of my invention. I
